Presbycusis and Fitness to Fly

Abstract

BACKGROUND: When a pilot is referred for presbycusis, his flight fitness may be questionable. The objective of this retrospective study was to describe a case series of presbycusis in a pilot population and to discuss the decisions about their flight waivers.METHODS: There were 19 pilots who were referred to the ENT-Head and Neck Surgery Department of the National Pilot Expertise Center. Their medical files were retrospectively examined.RESULTS: Of the 19 patients, 5 did not obtain flight fitness waivers. Among the 14 who received waivers, 7 had no restrictions on their flight fitness.DISCUSSION: Flight fitness was based on the maximum percentage of speech recognition and the slope of the curve for speech recognition in speech audiometry in noise and the follow-up of these findings. The results made it possible to determine a patient's fitness to fly with a waiver, which may be associated with restrictions. In our series, only 5 pilots out of 19 did not obtain a flight fitness waiver. The few published studies on the resumption of flight for patients who had presbycusis and our experience in France with similar waivers in commercial and military aviation suggest that under certain conditions and after relevant cochlear assessment, presbycusis may allow for a safe pursuit of aviation activity.Ballivet de Régloix S, Genestier L, Maurin O, Marty S, Crambert A, Pons Y.
